184 PLANT PROPAGATION 
VisurnuM.—Insert cuttings of half-ripened shoots in 
a shady border under a handlight or in cold frame in 
September, or put down layers in October. 
VICTORIA REGIA.—Treat this noble aquatic as an 
annual. Sow in pots in January seed that has been kept 
in water to preserve its vitality, and submerge 2 inches 
below the surface in a light position in water kept at a 
temperature of 85 degrees. Prick out, repot, and trans- 
plant as growth proceeds. 
VINCA (PERIWINKLE).—Increase hardy sorts by division 
in autumn or spring; stove sorts by cuttings of young 
shoots inserted in a close case with bottom heat in 
spring. 
VinE.—The Grape Vine is usually propagated by eyes 
in January or February, selecting well-ripened shoots 
with plump buds of the previous season’s growth from 
prunings that have had their lower ends stood in moist 
soil. They are prepared by cutting the shoot through 
in a slanting direction 4 inch above and the same distance 
below a bud, as shown in illustration on p. 33. These 
are planted horizontally with the bud uppermost, either 
singly in small pots or several in pans, filled with sand 
and loam, the top of the bud being just level with the 
surface soil. They are watered and plunged in a 
bottom heat of 80 degrees and a top temperature of 
65 to 70 degrees. When the buds begin to grow they 
are very tender and must be sheltered from cold 
draughts and always watered with tepid water when 
necessary to keep the soil moist. When roots and a 
little growth have started (see illustration on p. 33), 
those in pans are transferred singly into 3-inch pots, 
grown on with care in a hot, moist atmosphere, shifted 
to larger pots as growth proceeds, well ripened in
